Winspace has launched the G5, a new gravel race bike designed to combine aerodynamic efficiency and race-focused handling with clearance for some seriously large tyres.
The G5 follows the Chinese brand’s G3 gravel bike and uses a T1100/T800 carbon-fibre frame, with Winspace claiming a 950g frame weight in a size medium and clearance for 58mm tyres.
The bike is available in six sizes and four colours, with geometry aimed squarely at fast gravel riding rather than bikepacking.
Prices start at £1,650 / $2,200 / €1,933 for the frameset, or $2,350 with Winspace's Adventure Handlebar, making it significantly cheaper than Factor's recently released Elara frame package, which starts at $5,999 / €7,199.
Complete bikes range from $4,799 for a Shimano GRX RX825 Di2 build to $5,999 for the top-spec SRAM Force AXS version, with both builds including the Adventure Handlebar and Lún GRAPID 2 wheels. In between them is a SRAM Rival AXS build priced at $5,199.
That makes the G5 a compelling value proposition when compared to Specialized’s S-Works Crux 5 with Red AXS XPLR, priced at £11,999 / $14,000, and Cannondale’s SuperX Lab71, priced at £10,800 / $12,499.
There's also an optional suspension fork for riders looking beyond smooth gravel, with a RockShox Rudy Ultimate XPLR adding 30mm of travel and a full lockout for an additional $500.
Winspace is one of a growing number of Chinese cycling brands establishing itself in the Western market, having built its reputation around carbon bikes and components alongside its Lún wheel brand.
Aero gravel with wide clearance
The G5's most notable feature is arguably its tyre clearance. Winspace claims room for 58mm tyres at the front and 53mm at the rear, giving the bike considerably more scope for wide rubber than many gravel race bikes.
The company doesn't specify the rim and tyre combination used to establish those clearance figures, so actual compatibility will likely depend on the setup.
The frame uses a T1100 and T800 carbon-fibre composite construction, with the quoted 950g figure applying to an unpainted, uncut size-medium frame.
Geometry varies across the six sizes, with head angles ranging from 70.5 degrees on the XS to 71.5 degrees on the larger frames.
The seat angle is 73.5 degrees across the range, while chainstay length runs from 423mm to 427mm.
Winspace has given the G5 fully integrated cable routing, a T47 threaded 68mm bottom bracket and a 1-1/2in FSA ACR headset system. There's also internal storage accessed through a removable magnetic cover.
The frame uses flat-mount disc brakes with 160mm rotors front and rear, while a 180mm front rotor is also supported.
Axle spacing is 12x100mm at the front and 12x142mm at the rear, and the frame is compatible with both mechanical and electronic drivetrains. Maximum chainring sizes are 50T for a 1x setup and 48/36T for a 2x.
The optional Rudy Ultimate XPLR fork is designed as a bolt-on upgrade, with the brand saying its 30mm of travel is intended to take the sting out of rough surfaces, while retaining a full lockout for smoother sections and climbs.
With its combination of race geometry, aerodynamics, unusually generous tyre clearance and an accessible price, the G5 is an interesting proposition on paper.
